Prince builds upon the vaunted Beast XP string by introducing the new Tour XP 15L Tennis String Red polyester string. The XP stands for Xtra Power, which this string provides. Its monofilament thermo-poly construction results in a string capable of explosive power while still retaining a high level of precision. Tour XP provides an optimum balance of control, power, spin and feel as well as the same excellent tension maintenance that was a hallmark of Beast XP previously. The thick, 15L gauge yields the maximum durability while sacrificing some feel and spin potential. This string is an excellent choice for players seeking the durability of polyester in a package that maximizes all-court playability and possesses excellent tension maintenance.
